Product Description

   Lignite dryer or lignite coal dryer is a drying machine mainly used for drying lignite coal. Traditional drying method adopts centrifugal machine for dehydration, and the equipment is expensive and has low production capacity and small dehydration extend. Generally it can only reduce about 10% of the water and there is still 15%-20% of water content. Lignite rotary dryer adopts the new technology of first crushing and scattering the lignite coal and drying it with heating power, making the drying disposal of the materials realize continuity, industrialization and automation. The water content of the moist lignite coal processed by brown coal dryer can be reduced from 25%~30% to below 13%, and the moist lignite coal can be used as bunker coal, thus improving the coal washing and dressing technology and having excellent economic, social and environmental benefits.

lignite dryer

  Wet coal slime/coal slurry/lignite are evenly sent to rotary drum coal slurry dryer by feeding conveying system. After entrance into rotary dryer, wet materials will be led to oblique lifting area. Under the function of internal lifting plate, raw materials will fully exchange heat with hot air and evaporate partial moisture. Meanwhile, temperature of hot flue gas will drop sharply. Preheated wet materials enter medium drying stage and majority moisture will be evaporated here. Materials and flue gas will repeatedly mix and exchange heat until reach to ideal final moisture. Then, qualified dried materials will be discharged out dryer drum and sent to appointed place for storage. Hot air produced by heat source will enter dryer drum. After finishing heat exchanging, tail gas which contains large amount of vapor and dust will pass through cyclone and discharged to atmosphere after secondary purification of bag filter or water type dust removal system. 

Strength

 
Larege drying capacity

Lignite dryer holds strong over load reistance, large capacity, low energy consumption and low drying cost. Special structure greatly reduces equipment abrasion and enlarge service life.

 
High thermal efficiency and low energy consumption

There are various inlet temperatures. This machine can make the materials at outlet presented as small particles or powder which provides convenience for next process.

 
Great handling capacity 

There is a whole set of equipment which holds 10 to 200t/h output capacity. We can also customize drying machine according to customer’s demands.

 
Reasonble design

Reasonable design can avoid the leakage of materials.It adopts special seal structure made from tin steel piece between cover body and machine, which prevents leakage under micro negative pressure.
